The halogens making up group 17 on the Periodic Table have seven electrons in their outer shell. The five highly reactive elements in this group are Fluorine, Chlorine, Bromine, Iodine, and Astatine.

∙ 15y agoA Group 7 element is one in the series of elements in group 7 (IUPAC style) in the periodic table, which consists of the transition metals manganese (Mn), technetium (Tc), rhenium (Re), and bohrium (Bh). All of these elements are classed in Group 7 because their valence shells hold seven electrons. Technetium has no stable isotopes. Technetium and promethium are the only two such elements before polonium, after which no known element has a stable isotope.

Fluorine , Chlorine, Bromine, Iodine, Astatine, & Tennessine.
The last two are radio-active and not fully characterised.

Do group 7 electrons have 7 electrons in the outer shell?
Group seven elements have 7 electrons in their outermost energy level.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Why are group1 and 7 found as compounds?
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
What do all elements in group 7 have in common?
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
Do group 7 electrons have 7 electrons in the outer shell?
Group seven elements have 7 electrons in their outermost energy level.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
Group of elements with 7 valence electrons?
Halogens

Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
What do all elements in group 7 have in common?
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
The number of electrons in the outer energy level of Group 17 elements is?
there are 7 electrons in the outer energy level of group 17 elements
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
How many valance electrons does halogen have?
Halogens are group 17 elements. They have 7 valence electrons.
What is the name of the group that contains elements with 7 valence electrons?
"Halogens"
